with a gouging thrust that would have torn out the eyes of a slower man, following it up instantly with a savage kick for the groin. No automaton this, geared and set to perform certain fixed duties with mechanical precision, but a lithe, strong man in hard training, fighting with every foul trick known to his murderous ilk. But Costigan was no tyro in the art of dirty fighting. Few indeed are the maiming tricks of foul combat unknown to even the rank and file of the highly efficient Secret Service of the Triplanetary League; and Costigan, a Sector Chief of that unknown organization, knew them all. Not for pleasure, sportsmanship, nor million-dollar purses do those secret agents use Nature's weapons. They come to grips only when it cannot possibly be avoided, but when they are forced to fight in that fashion they go into it with but one grim purpose--to kill, and to kill in the shortest possible space of time. Thus it was that Costigan's opening soon came. The pirate launched a particularly vicious kick, the dreaded "coup de sabot," which Costigan avoided by a lightning shift. It was a slight shift, barely enough to make the kicker miss, and two powerful hands closed upon that flying foot in midair like the sprung jaws of a bear-trap. Closed and twisted viciously, in the same fleeting instant. There was a shriek, smothered as a heavy boot crashed to its carefully pre-determined mark: the pirate was out, definitely and permanently. The struggle had lasted scarcely ten seconds, coming to its close just as Bradley finished blinding and deafening the robot. Costigan picked up the projector, again donned his spy-ray goggles, and the two hurried on. "Nice work, Chief--it must be a gift to rough-house the way you do," Bradley exclaimed. "That's why you took the live one?" "Practice helps some, too! I've been in brawls before, and I'm a lot younger and maybe some faster than you are," Costigan explained briefly, penetrant gaze rigidly to the fore as they ran along one corridor after another. Several more guards, both living and mechanical, were encountered on the way, but they were not permitted to offer any opposition. Costigan saw them first. In the furious beam of the projector of the dead pirate they were riven into nothingness, and the two officers sped on to the room which Costigan had located from afar. The three suits of Triplanetary space armor had been sealed into a cabinet whose doors Costigan literally blew off with a blast of force, rather than consume time in tracing the power leads.
